Be it known that I, JEFFERSON M. Giana -NER, a citizen of the UnitedStates, residing .at New London, in the county of New Loni don and Stateof Connecticut, have invented E certain new and useful Improvements inCotton Bolling, Cleaning, and Grinning Machines; and I do declare thefollowing to be a full, clear, and exact description of the in vention,such as will enable others skilled in the art to which it appertains tomake and use the same.

My invention is an improved machine for separating cotton from itsbolls, cleaning the cotton, and removing the lint from the seeds,

its object being to enable cotton to be gathered in the bolls and toremove the cotton from the bolls, thus obviating the necessity ofpicking the cotton from the bolls by hand, which is the usual method ofharvesting cotton.

A further object of the invention is to provide means for cleaning thecotton and dis- "chargin all boll particles, dust, leaf-trash, .and: oter foreign substances therefrom 'while the cotton is being removed fromthe bolls.

.-With these and other objects in view the invention consists in theconstruction, combination, and arrangement of devices herein -'shown anddescribed, and particularly p0int ed out in the appended claims.

In the accompanying drawings, Figure 1 is and cleaning machine,embodying my invention. Fig. 2 is a side elevation of the same. Fig. 3is a similar view showing the opposite side of the machine from thatshown in Fig. 2. Fig. 4 is partly a side elevation and partly a verticalsectional view showing a modified construction of my improved bolling,cleaning, and ginning machine. Fig. 5 is a detail top plan view which ispartly a section on the plane indicated by the line a a of Fig. 1. Fig.6 is a detail perspective view of one of the ribs which operate in thespaces between the saws' of the saw-cylinder, and Fig. 7 is a similarview showing the construction of one of theribs shown in the lower artof-Fig. 4 which operate in the spaces between the saws of thesaw-cylinder in the modified form of the invention shown in Fig. 4.

- COTTON BOLLING, CLEANING. AND emume MACHINE.

I-atentecl July 10, 1906."

black-seed species of cotton in which the fiber adheres to only one endof the seedi-i I will. first describe the form of my invention shown inFigs. 1 and 2, which is specially adapted for bolling and cleaningcotton and putting it in condition to be ginned. In the upper portion ofthe frame 1 is an inclined trough 2, which has a dischar e-opening '3 inits lower side at the u per en of the trough, and in the said trough 1san endless-feed belt I or apron 4, provided with slats 5, which slatshave projections whereby the cotton is engaged by the upper lead of theendlessbelt. The said belt operates on the ,rollers'6 7, and the shaftof the roller 7 is provided at one end and on the outer side of the saidtrough with a wheel 8, which is provided with spur-teeth 9 and is alsoprovided with ratchet-teeth 10. Above the trough 2 is a hop er 11, thebote tom of which is formed by t e upper lead of I the endless belt.Near the up er end of-the said hopper and over the discharge portion ofthe upper lead of the feed-belt 4 is a trans-a versely-dlsposedoscillating leveling-board- 12, which is hinged-at its upper side, as at-13 8o 1 is provided on its rear side at its lower edge.

with a cross-bar 14, from which project rearwardly and downwardlyextending points or. teeth 15, said leveling-board being furtherprovided at its ends with outwardl -extend+l 8 5 mg studs 16, whichproject throu and op j erate in curved slots 17, made in t e sides ofthe hopper 1 1 and which are concentric with the pintles of the hinges13. A rocker-18 is pivotally mounted on one side of the frame, as at 19,and has an arm 20, which is, providedwith a slot 21. A ulley 22, whichis mount ed on one side of t e frame, is provided with a crank-pin 23,to which is connected one end, 1 of a pitman 24, the opposite end ofthepitman being pivoted to a block which is ad-a justable in the slot 21,whereby the throw of the rocker may be regulated. Said arm 20' cf therocker is connected to one of the studs 16 of the oscillatingleveling-board by meansj' '1oo of a link 25, said link being alsoconnectedto i the said rocker. The rocker is provided with a pair ofreversely-operatin pawls 26, which engage the ratchet-teeth o the wheel8 and WhlCh when actuated'by the rocker I8 willserve to rotate saidwheel 8 by a stepby-step movement, as will be understood. Hence motionis imparted to the endless feed-belt. The cotton inthe bolls is drawnfrom the hopper 1]. by the movement of the no endless feed-belt 4, thequantity of cotton discharged from the hopper by the said feedbelt beinregulated by the oscillating leveler 12, as will be understood. Theslats of the endless feed-belt en as they pass over the roller 7 anddrop t e bolls through the 0 ening 3 onto a revoluble spiked roller 27,\v 'ch is provided at one end of its shaft with a inion 28, which isengaged by the s ur-teet of the wheel 8. Hence the said spi ed roller isrotated at a higher rate of speed than the roller 7 and in the directionindicated by the arrow in Fi 1 and serves to regulate the discharge 0through the said opening.

In a chamber 29 below the opening 3 is mounted a pair of ribbed rollers30 31, the shafts of which are respectively provided with a spur-wheel32 and a inion 33, which intermesh and cause the sald shafts to revolvesimultaneously in opposite directions and at diflerent rates of speed toproduce a crushing and rubbing effect'on the bolls which pass betweenthem. The shaft of the roller is here shown as mounted inmovable'bearings 34, which are pressed in one direction b the springs35. The shaft of the roller 31 as a pulley 36. p

Below the opposing sides of the rollers 30 31 in the lower portion ofthe chamber 29 is a deflector 37, which directs the cottonbolls frombetween the rollers 30 31 into a chamber 38. In the lower portion of thesaid chamber 38 is a semicylindrical foraminous breast 39, which forms acover for an opening in an outer wall of said chamber and in whichrotates a toothed roller 40, the shaft of which is provided with-a ulley41 at one end. In the rear side of the ower portion of the cham ber 38is a deflecting element 42, which is pivotally mounted and thepivot-shaft 43 of which has its bearings in the side of the frame 1 andis rovided at one end with an adjusting qua rant-arm 44, by means ofwhich said deflecting element may be disposed at any requiredadjustment. Said defleeting element has concave faces which arerespectively opposed to the saw and toothed cylinders. Said deflectingelement forms a contracted throat 45 in the lower portion of the chamber38 and immediately above thetoothed roller 40 and is rovided on itsunder side with teeth 46, w ch are disposed in staggered relation andbetween which the teeth of the roller 40 pass as said roller rotates. Atthe upper s1de of the said deflecting element is a presser-bar 47, whichis pivotally mounted, as at 48, and the shaft of which is provided atone end with an adjusting quadrant-arm 49, whereby the said presserbarand the fingers 50, with which it is provided and which project upwardlyand rearward ly therefrom, may be adjusted. A valve 51 is laced in rearof the roller 40, which valve regu ates an opening 52 the lower side thebollcotton downwardlyof which is formed by a forwardly and downwardlyinclined deflector 53. Said valve permits the eflective area of saidopening to be varied as may be required and may be adjusted by means ofa quadrant-arm 151. On a shaft 54, which is mounted in rear of thedeflecting element, is a saw-cylinder which comprises a series ofalternately-disposed saws. 55 and s acers 56. Said spacers are ofsuitable widt according to the required s ace between the saws, and thediameter of t e said spacers is considerably less than that of the saws,so that annular openings or channels are formed between the said sawsaround the said spacers, which channels communicate with the interior ofthe chamber 38 and with the discharge-opening 52 thereof, which isregulated by the valve 51. The presserfingers 50 are disposed oppositethe spacers between the saws and over the same and may be adjusted asmay be required with relation to the said saws. Above the sawcyl inderis a bar 57, which is carried by eccentrics 58, which are mounted insuitable bearings in the end of the frame or casing 1 and which areprovided with adjusting-arms 59, whereby the said bar may be raised andlowered. Ribs 60 are attached to and depend from the said bar and extendbetween the upper portions of the saws of the sawcvlinder. The lowerportion of each of said ribs where it is below the upper edges of thesaws is widened at its front side, as at 61. The portion of each ribabove the said widened portion 61 is contracted in width to formpassages 62 between the ribs for the clearance of the seed-cotton and topermit cotton and seed to be carried by the saws past said ribs. Atoothed doffing-roller 63 is mounted above the saws of the saw-cylinderand in the rear side of the upper portion of the chamber 38, and itsshaft is provided at one end with a pulle 64. The dofling-roller 63 isrotated at a' igh rate of speed and serves, as hereinafter described, toknock the bolls from the cotton, return the bolls to the chamber 38, andkeep the spaces clear between the ribs. In rear of the saw-cylind er isa revolving brush 65 for removing the cleaned cotton from the saws andthe shaft of which brush is provided at one end with a pulley 66.

A chamber 67 is below the openin 52 and is fed through the said opening.In t e lower portion of said chamber is a toothed roller 68, which isidentical in construction with the roller 40, hereinbefore described.Above the said roller 68 and slightly in advance thereof is apivotally-mounted deflecting element 69, which is similar inconstruction to the defleeting element 42, hereinbefore described, excetmg that it is not provided with teeth.

At t e upper rear side of the deflecting elestasis ment 69, and overthis cylinder is a doffingroller 72, which is identical in constructionwith the doffing cylinder or roller 63, herein- 'before described. Adischarge-opening 73 required extent.

a revoluble brush 65.

at the lower side of the chamber 67 is formed between and below thetoothed roller 68 and the cylinder 71 and is provided with a valve 74,by means of which its effective area may be regulated-that is tosay,said valve serves to partly close the said opening to any Said valve maybe adjusted as may be required by means of a quadrant arm 174. In rearof the saw-cylinder is The latter is in a chamber 76, which has adischarge-opening 77 at its rear side. The brush 75 is in a chamber 78,which is below the chamber 7 6, is separated therefrom byawall 79, andsaid chamber 78 is provided on its rear side with a discharge-opening80. The shaft of the roller 68 is provided at one end with a pulley 81.The s aft of the doffing-roller 72' is provided at one end with a pulley82.

The shaft of the cylinder 71 is provided at one end with a pulley 83. Astub-shaft 84 pro'ects from one side of the frame or casing of t emachine, and on the said shaft are pulleys 85 86, which revolvetogether. Said pulley 86 is smaller than the pulley 85. An endless belt87 connects the pulleys 83 85. An endless belt'88 connects the pulley 86with the pulley 22. An endless belt 89 connects the pulleys 36, 64, 41,82, and 81 and also engages idler direction-pulleys 90 190, which arerespectively between the pulleys 64 and 41 .between the latter and thepulley 82. The pulley 90 is a belt-tightener and has its bearings in anadjusting-arm 191. The shaft of the cylinder 71 is provided at the end 0posite the ulley 83 with a pulley 91. Tl ie shafts of t e brushes 75 65are respectively provided at the same end with pulleys 92 66, and theshaft 54 of the saw-cylinder has apulley 94 at the same end. Adriving-belt 95 engages and connects sa'id pulleys 91 92 66 94, andhence serves to drive the saw-cylininder, the card-cylinder, and therevoluble brushes. i

In the operation of the machine the cotton after its bolls have beenrubbed and crushed by the rollers 30 31 passes, together with thecrushed bolls, into the chamber 38 and is caught by therapidly-revolving toothed cylinder 40, the teeth of which coact with theteeth of the element 42 to further disintegratethe bolls and to throwthe cotton against the saws 55 and such particles of the bolls as may beseparated from the cotton mto the openmg52. The saws 55 carry the cottonupwardly on their front sides, together with the remaining bolls andunder the resser-fingers 50, whichlatter cause the cotton to adhere tothe saw-teeth. The widened portions 61 of the ribs between the sawsserve to move the cotton upwardly to the peripheries of the saws as thecotton passes under the dofiing-roller 63. This dofiing-roller 63rotates rapidly, and its teeth serve to arrest the passage of the bollsand to throw them back onto the cylinder 40. The

seed-cotton, which is thus freed from the bolls, is carried by the sawspast the ribs 60 (the openin s between the narrowed portions 62 of theri s permitting the seedcottonto pass) and is removedfrom the saws bythe action of the brush 65, which revolves at a higher rate of speedthan the saws. Said brush also discharges the seed-cotton through theopening 77 The brush also serves to create a blast of air which isdirected forwardly through the passages formed by the spacers 56 of thesaw-cylinder and outwardly throu h the lower portion of the chamber 38,the b ast escaping through'the foraminous wall 39 and carrying with itdust and leaftrash, together with other minute forei n particles whichare whipped loose from t e fiber by the teeth of the roller 40. Such ofthe material as remains after having been thus treated by the toothedcylinder or roller 40, the saw-cylinder, the resser-fingers 50, the ribs60, and the dofiing roller or cylinder 63 is fed from the opening 52into the lower chamber 67, where it is similarly acted upon by thetoothedcylinder 68, the resser-fingers 70, the carding-cylinder 71,andthe doffing cylinder or roller. 7 2; The revoluble brush 75 takes theseed-cotton from the carding-cylinder and discharges it thro h theopening 80. The machine may be'a apted for ginning sea-island and otherblack-seed species of cotton by removing the feed mechanism,crushing-rolls, ribs, saw-cylinder,--and dofling-rollers, (shown in Fig.1,) replacing such feed mechanism and crushing-rolls with an ordinarycotton-gin feeder A, as shown in Fig. 8, substituting acard-chthe'dgcylinder B for the saw-cylinder, and replacing thedotting-rollers 63 72 (shown in Fig. 1) with doffing-rollers C, in whichthe spaces between the teeth longitudinally of such rollers are so smallas to prevent the assage of the cottonseed past the dofiing-ro lers, sothat the latter serve to throw the cotton-seed back for retreatment. Thefibers engaged by the teeth of the card-clothed cylinder B will be takentherefrom by the brushes and discharged through the openings 77 80,while the seed will be finally discharged through the openin 73.

n the modified form of my invention shown in Fig. 4 and which is adaptedfor simultaneously bolling, cleaning, and ginning the green-seed speciesof cotton, in which the lint adheres to the entire surface of the seed,the feeder mechanism, crushing and rubbingmechanism, the uppersawcylinder 96,

toothed cylinder 97, doiling-cylinder 98, ribs 99, and brush are similarto the construction shown in Fig. 1 but the discharge-open ing 101 inthe lower side of the chamber 102 communicates with the exterior of thecasing on the front side thereof and is provided with the reulating-valve 103. The seed-cotton which has been freed from the bollsis taken from the cylinder 96 by the brush 100 and discharged into thefeed-hopper 104, in the lower portion of which is mounted a toothedfeed-cylinder 105, adjacent to and back of which is a saw-cylinder 106.Above the feedcylinder 105 and adjacent to the saw-cylinder is a tootheddoifing-cylinder 107. Above the saw-cylinder is a chamber 108, thebottom and front side of which are formed by a series of ribs 109, whichextend between the saws of the saw-cylinder 106 and each of which iscurved at its lower rear portion to bring the upper surface thereof nearthe periphery of the saw at the point nearest to the dotting-cylinder107, as at 110. Each rib is provided near its terminal end with alateral flange 111 and is further provided with a flange 112, whichextends nearly to the flange 111 to form a channel 113 between them,through which linted seeds may drop to and through a discharge-opening114, which is provided with a regulating-valve 115. The ribs 109 aresecured to and carried by a bar 116, which is pivotally mounted, as at117. A lever 118 is provided to operate a cam 119, by means of which thebar 116 may be turned to raise and lower the ribs 109. When the saidribs are raised, the cotton in the chamber 108 above the saws of thesaw-cylinder 106 is raised from and out of contact with said saws. Infront of the smr-cylinder 106 is a revoluble brush 120, which coactstherewith to draw the cotton fiber therefrom and force the same througha discharge-spout 121, which delivers the fiber to a condenser that isnot here shown. A discharge-openin 122 is below the engaging side of thesawcy inder 106 and brush and is provided with an adjustable mote-board123 of the construction usually employed in cottongms. The rear andupper portion of the chamber or roll-box 108 is formed by a movableboard 124. The rear board 125 of the said chamber is curved, as shown,and is provided with lugs 135, which have inclined slots 136. Studs 137,which project inwardly from the end walls of the casing, operate in saidslots. Links 126 project upwardly from the board 125and are pivotallyconnected to arms 127, which are fixed to a rod 138, which has itshearings in the end walls of the casing and is provided at one end witha lever-arm 139, (shown in dotted lines in Fig. 4,) whereby said rod maybe partly turned to cause the arms 127 and links 126 to raise or lowerthe said board. It will be understood that the slots 136 and studs 137Bessie cause the said board to move outwardly as it is raised to relievecompression on the roll. A pitman 130, which is pivotally and adjustablyconnected to said arm 129, is also connected to a link 131, which ispivotally mounted on one side'of the casing, as at 132, and is providedwith an u wardly-extending arm 133, provided with s ots through whichthe feed-pawls 26 pass. carried by the rocker 18, which is substantiallyidentical in construction with that shown in Fig. 1. The cottondischarged into the hopper 104 is caught by the teeth of therapidly-revolving feed-cylinder 105 and projected against thesaw-cylinder, which rotates in the same direction. The seed-cotton iscaught andcarried u by the saws of the cylinder under the rapily-revolving cylinder 107, which serves to arrest any bolls that aremixed with or adhere to the seedcotton and to throw the same back ontothe feed-cylinder 105, which feed-cylinder discharges the same bycentrifugal force through the opening 134. All the cotton adhering tothe teeth of the saws is carried over to the rapidly-revolving brush120, which serves to remove the same, as hereinbefore stated. Theseed-cotton at each engagement with the teeth of the saw-cylinder isonly partly deprived of its lint, so that it accumulates and forms aroll or mass which by the action of the saw-cylinder is rotated untilthe lint is entirely removed from the seeds. As fast as cleaned the seedpasses down through an opening 134. The mass of cotton and seed in theroll-box 108 controls the amount fed to the bolling and cleanin andginning mechanism by the feeder. hen said roll-box or chamber is full,an increase of the material therein moves the board 124 outwardly,

thereby causing the pitman 130 and link 131 to raise the feed-pawls 26from the teeth 10 of the wheel 8, and hence cut off the supply ofmaterial to the machine. As the quantity of material in the roll-box 108diminishes the board 124, by the means hereinbefore described, recngagesthe feed-pawls 26 with the gear 8, as will be understood. Hence themachine is prevented from becoming clogged by an excess of material fedthereto.

Said feed-pawls are In the drawings I show, and within the scope of myinvention I employ, the revoluble toothed cylinder, the dofling-cylinderspaced therefrom, and a deflecting element between said toothed anddoffing cylinders, in combination with a saw-cylinder and also incombination with a card-clothed cylinder.
